This review focuses on the critical role of MR neurography (MRN) in diagnosing and managing peripheral nerve injuries (PNIs). It emphasizes the ability of imaging to differentiate injuries that may heal spontaneously from those requiring surgery, using classification systems like Neuropathy Score Reporting and Data System with imaging findings corresponding to established electrodiagnostic grading systems. MRN also evaluates skeletal muscle denervation and is useful for differentiating pre-ganglionic from post-ganglionic traumatic injuries. MRN is an integral component of optimizing care for patients with PNI.
